IMPROVEMENT IN' SASH-FASTENER.

The Schedule-referred to in these Letters Patent and making part of thesame To all whom 'it may concern Be it known that I CORNELIUS H. GAIN,of Fremont, in the county of Sandusky, and State of Ohio7 have inventeda new and useful Improvement in Sash-Fasteners; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspccication.

This invention relates to improvements in sash-fast` eners, whereby itis designed to provide an improved arrangement of selilfastening device,to be released for moving the sash in either direction, by pressingthereon in the direction it is desired to move the sash, as will behereinafter described.

Figure l represents an elevation of a window having 'my improvementapplied to it, and

Figures 2 and 3 represent detail views of the same.

Similar letters of reference indicate corresponding parts.

A represents a oase, to be fastened to the stile of the sash, containingtwo bars, B, arranged to slide in the said case at oblique angles to thestile and the window-ii'ame, the one in an upward direction, and theother in a downward direction, the outer ends being provided withthumb-pieces, projecting through slots in the front plate ofthe case, topermit the application ofthe ingers for moving them.

The inner ends of the said bars carry rollers, D D, toothed on oneportion of the perimeter, and plain or slightly roughened on the other.

The toothed portion gears with racks E, correspondingly toothed, andsuitably supported in the case for the purpose.

The said rollers, or Wheels, are so arranged that the plain or roughenedportions will bear against the face of the window-frame, when the slidesare moved suliciently in that direction.

When the rollers are resting in the position represented in fig. 3, withtheir roughened surfaces bearing against the face of the window-frame,an effort to raise the window-sash, without also withdrawing the slideof the roller D, would cause the said roller to turn in the direction todraw it down tighter against the said frame, and wedge against it withsuch force as to prevent raising it; but if the slide of the said rollerD be raised at the same time, the sash may then be freely raised. Inlike manner, when the sash is to be moved downward, the slide of theroller D must be also moved downward, and will otherwise lock the sash.

The roller D will naturally bear against the jamb of the window-frame bythe action of gravity, but it may be necessary to move the roller D intocontact with the jamb when that one is required to act.

Having thus described my invention,

I claim as new, 4and desire to secure by Letters Patenti The slides B,carrying the toothed and plain or roughened rollers D D', combined withthe case A, provided with toothed racks E, substantially as and for thepurpose specied. v
